Robocall Reports for 02 3815 5731
One contributor has reported receiving a robocall from 02 3815 5731 (also written as 0238155731). The caller disconnected after the recipient answered, but the contributor noted distinct call centre background noise before the line went silent. This pattern is typical of robocall systems that dial multiple numbers simultaneously and disconnect when a human answers, often testing whether a number is active.
What Happened When the Contributor Answered
The contributor who took the call from 0238155731 heard a call centre environment in the background, including what sounded like multiple conversations and office noise. However, no person addressed them directly, and the call ended shortly after. The contributor couldn't determine what the robocall system was trying to accomplish, whether it was attempting to deliver a recorded message, transfer to an agent, or simply verify the line was active.
Why Robocalls Use Call Centre Backgrounds
Robocalls that play call centre noise in the background are often used by scammers or aggressive telemarketers to appear as though they're calling from a legitimate business operation. The background noise is sometimes pre-recorded and designed to make the call seem more credible. When recipients answer, the system may disconnect if the caller list indicates the number belongs to someone who has previously rejected or reported similar calls, or it may be a system malfunction where the automated dialler lost its connection.
What to Do If You Receive a Call from 02 3815 5731
If 02 3815 5731 calls you:
- Do not: Call the number back, as robocalls often use spoofed numbers and returning the call could connect you to an unrelated service or scammer
- Do: Let the call go to voicemail if possible, or hang up immediately if you answer
- Do: Block the number in your phone's native call blocking settings
- Do: Note the date and time if you receive multiple calls from 0238155731
How to Report 02 3815 5731

WRITE A REVIEWFrequently Asked Questions
What is a robocall and why did 02 3815 5731 disconnect when I answered?
A robocall is an automated dialling system that calls multiple numbers at once. When 0238155731 disconnected after you answered, it likely means the system lost its connection, the call was testing whether your number was active, or the dialler's queue had moved on to the next number. The call centre background noise suggests it was a system designed to simulate a real office environment.
Should I call back 0238155731 if I see a missed call?
No. Do not call back 02 3815 5731. Robocall systems typically use spoofed or temporary numbers, so calling back won't reach the original caller and may connect you to an unrelated service or scammer. It's better to block the number and ignore any missed calls.
Is 02 3815 5731 a legitimate business number?
Based on the community report for 0238155731, it appears to be registered to Symbio Networks Pty Ltd as a local service in NSW. However, the robocall behaviour reported suggests the number may be spoofed (appearing as this number but actually being called from elsewhere) or the service is being misused. Legitimate businesses don't typically disconnect unexpectedly with call centre noise in the background.
Can I block 02 3815 5731 on my phone?
Yes. On most Australian mobile phones and home phones, you can block 02 3815 5731 directly from your call log or through your phone's settings. If you're using a landline, your phone provider may offer call blocking through their network (contact them directly). For further protection, you can also register with the Do Not Call Register at donotcall.gov.au.
What should I do if I receive multiple calls from 0238155731?
If you receive repeated calls from 02 3815 5731, block the number immediately and report it to the ACMA at acma.gov.au. Document the dates and times of each call. If the robocall includes any spoken claims about money, threats, or requests for personal information, also report it to Scamwatch at scamwatch.gov.au.
Why does 0238155731 have call centre background noise?
Robocall systems sometimes play pre-recorded call centre background noise to appear more legitimate and less automated. This tactic is used to make the call seem like it's coming from a real business office rather than an automated dialling system. When you answer, the system may disconnect if it wasn't expecting a human response or if the call was simply testing whether your number was active.
